Orthotropic Material type for ply

Recommended Posts

Hi everyone,

 

I am trying to model a helicopter blade, i have imported the CAD model.. etc until i created Plys.

whenever i set the material type to orthotropic and hit update, at the bottom left it says "cannot compute material normal" and when i go back into the ply, the material type is back again to "all".

 

would you be able to help me with this issue?

 

Kind Regards,

Mohamed

Hi Mohamed,

 

I am able to see results when I used the file you shared, as it is in HW 14.0 Student Edition.

 

What is the version of HyperWorks are you using?

Hi Prakash,

 

Yes i do get results when i run the model, however in the model it does not allow me to set the ply material type to 'orthotropic'.

I see the text "Cannot compute material normal" on the bottom left on the 'Status bar' when i click ok after changing the material type to orthotropic. When i open the ply definition, i find it has changed the material type to 'All'

 

I am not sure if using the material type 'All' is accurate for composites.

 

Correct, I am using HW 14.0 Student Edition.

 

Thanks,

Mohamed

Hi Mohamed,

 

I am able to create ply with material type as Orthotropic without any issues. Since you are referring to right material there is no problem with the modelling. Changing Orthotropic will only filter Ortho material types from a list of mixed materials.

 

Yes, you can use the model created on HW Student Edition in your university's full edition.
